Hi
After I compile a js source with v8, I would like to get the method/member per request  
Any idea how to do it ?

For example for user i want to see : User & sayHi method and for AA i want to see the Z & b keys

const char * src= ("const AA = {Z: 5, b : 6 } ;  class User { User() {alert('con');} sayHi() {alert('hi');}}  let user = new User()");

Local<v8::String> source = v8::String::NewFromUtf8(m_Isolate, src);

// Compile the script and check for errors.
Local<Script> compiled_script;
if (!Script::Compile(m_Context, source).ToLocal(&compiled_script)){
}
...

Thanks
